Why You’ll Love This One

If you’re looking for an easy way to up your fiber intake and improve your digestive health, this smoothie is packed with 13 grams of dietary fiber from whole food ingredients. It’s great for busy mornings or any time you need something quick and simple.

It’s recommended that women get at least 25 grams of fiber per day and men get at least 38 grams of fiber per day. It can be a challenge to get enough fiber in, so starting the day with a fiber-packed breakfast can be a great way to kick it off.

Eating enough fiber helps to keep you full and satisfied so that you’re less likely overeat, helps to stabilize your blood sugar levels so that you get less cravings, and supports your gut health! The protein content is great too; this smoothie packs 23 grams of protein to keep you nice and full!

Getting your fiber in doesn’t have to come in the form of bland bran flakes or foods that you don’t like. The best part about this smoothie is that it’s absolutely delicious! Plus, there’s no veggies in sight. If you’re not a big fan of veggie-packed smoothies, you’ll love this high-fiber smoothie recipe.

Ingredients for a high fiber smoothie

Ingredients You Need

Frozen mixed berries: One of my favorite high-fiber foods are frozen berries because 1) they’re packed with fiber and 2) they’re cheaper and last longer, and 3) they add just the right amount of ‘frozen’ to the smoothie so that you don’t need to add ice!

Greek yogurt: Greek yogurt adds gut-healthy probiotics that go hand in hand with the fiber, creaminess, and protein to keep you full and satisfied! Adding Greek yogurt is a simple way to make the smoothie filling enough to be adequate for an entire meal! I like to choose one with no added sugar.

Chia seeds: Chia seeds are a great source of fiber and omega-3 fatty acids, too! A tablespoon of chia seeds is a great addition to oatmeal, smoothies and yogurt for extra fiber. You can find chia seeds at your local store or buy them online!

Oats: Have you ever added whole grains to a smoothie before? Oats a great source of soluble fiber and they blend really easily into smoothies! I love this kind from Bob’s Red Mill.

Banana: No fruit smoothie is complete to me without at least half of a banana. It completely transforms the texture of the smoothie and adds just the right amount of sweetness. Freeze the other half to throw into your next smoothie! You can use a fresh banana or frozen banana!

Almond milk: I love using almond milk in fruit smoothies because it’s creamy and light, but you can use any almond milk that you like.

How To Make It

  1. Throw all of your ingredients into a high-speed blender. This Ninja system is my absolute favorite. Blend on high for 20-30 seconds until smoothie is smooth and creamy.

More High-Fiber Ingredients Ideas for Smoothies

Here are more high fiber smoothie additions that you can add to your next high fiber smoothies!

  2. Frozen veggies like riced cauliflower, zucchini or even riced broccoli give the smoothie a creamy, milkshake-like texture and add a big nutrition punch!
  3. Seeds like hemp seeds, flax seeds, pumpkin seeds, or sunflower seeds add fiber, protein and healthy fats to your smoothie.
  4. Avocado: Avocado blends perfectly into smoothies, adds a mild nutty flavor and makes a super creamy smoothie. Plus, they’re a great source of healthy fats and fiber!
  5. Cocoa powder: Cocoa powder is a shockingly high fiber food. Did you know that 1 tbsp of cocoa powder has 2g of fiber? Add 1-2 tbsp of cocoa powder to add fiber and turn your smoothie into a chocolate variety!

Variations + Substitutions

  • Add peanut butter or almond butter for a PB & J style smoothie
  • Add a handful of leafy greens for more fiber and nutrition
  • Swap the Greek yogurt for a scoop of vanilla or chocolate protein powder for another option to make it filling enough to be a meal replacement.
  • Add a splash of fruit juice, a teaspoon of honey, or a teaspoon of maple syrup if you want it to be a more sweet smoothie.
  • Use coconut water and a splash of pineapple juice instead of milk for a lighter, more tropical tasting delicious smoothie.
  • Use other fresh fruits or frozen fruits like strawberries, mango or kiwi.
  • Make a double batch and throw extra into popsicle molds for a high-fiber frozen treat!
